synthesis, characterization and thermal analysis of cr(iii), mn(ii) and zn(ii)complexes of a new acidicazo ligand

The researchers wanted to make a novel azo imidazole as a follow-up to their previous work. we focused on the ligand 4-[(2-amino-4-phenylazo)- methyl]-cyclohexane carboxylic acid as a derivative of trans-4- (aminomethyl) cyclohexane carboxylic acid diazonium salt, synthesized a series of its chelate complexes with metal ions, and characterized these compounds using a variety techniques, including elemental analysis, ftir, lc-mass, nmr and uv-vis spectral process as well tga, conductivity and magnetic quantifications. analytical data showed that the cr(iii), mn(ii) and zn(ii) complexes out to 1:1 metal-ligand ratio with octahedral geometry except mn complex has tetrahedral geometry.
